@spookcity138 That's the log with v2.0, selinux enforced.
I've uploaded it in the post before, but it was not there and so I posted the log again.
OK, thanks for clarifying. The most obvious thing to me is:
[3] init: Untracked pid 26739 exited with status 0

There are other errors dealing with rmnet0 that happen many times, but this has to do with network interfaces, so I'm unsure how that's related. The init untracked pid errors seem to be definite problems though. I'll have to try to look into that some as I really don't know.

So this may only happen to me but it's happening on BOTH of my minis. Has to do with the parsing issue discussed on AEX thread.
I'm on Xenon atm and with a clean flash there is no parsing error, BUT with Total Commander files can't be moved or copied to or deleted from SD card (external).
With MiXplorer everything is ok (with original ROMs kernel).
Then I flashed Kernel test9 and suddenly Mixplorer also couldn't move, delete or copy...restored boot with TWRP and back to where I was.
Then flashed Kernel v3.0 and suddenly BOTH file explorers can move or copy or delete (external, 64GB Samsung card, but also tried San-Disk...doesn't matter).
But guess what..now there's that parsing error, which wasn't there with the original kernel????.
Both parsing and moving error occur not on every clean flashed ROM together, but most 7.1.2 ROMs I tested have at least one of them (all but Validus, but haven't tested kernel there).
So strange things are happening on my side...but it's on both devices...no issues on 7.1.1 ROMs btw...

The "moving error" could be related to some privilege issues. I'm just assuming this because of the changelog from MiXplorer that states: "Improved to gain permissions for SD card without 'Files' app on Nougat+". So maybe it has something to do with that "files" app. On some ROMS this app can't access the internal sd card.

Hmm,this is indeed really really bizarre. I sadly have no idea what may be causing this. I always use Mixplorer so I can only speak to that,but have not had any of these issues with any of my kernel builds. I will try to look into this some. I know I said I would,but have been really busy. If anyone else has a similar issue, be it with my kernel or not,please tell. Its a weird thing.

Edit:
If you haven't already and are able to back stuff up,it might be worth it to format the card on a computer. I really don't know at this point. Just throwing things out there.

This "files" app is that the one to access external sd card from the storage setting (where the card also can be ejected)?

If it's only on my side it doesn't really matter and yes I formatted on a computer and also a different card. Ah well...poor little guinea pig is getting used up...will live with that. Thanks guys.

Boot Animation gets stuck after installing the Kernel. I also tried to flash it Clean with the Rom. Always wiped dalvik and Cache. No solution so far...

I am on crdroid 3.6, 7.1.2.

That one works.

So, the Problem ist the Rom? Does it Work with rr?
Yeah,the issue is your phone. More specifically the revision of your CPU. Nothing you can do about it.
That version will work with all the custom nougat ROMS. There are more people who have the problem with the overclock. That's too bad. I will be releasing builds with a 1.5 version on my github here;
https://github.com/Spookcity/ROMS-G800F/issues/21
I'm not going to post them up here though,sorry. There's just not enough people that the 1.6 version doesn't work for. Just check my github for newer releases of the 1.5 version

Had the same when I first flashed version 3.0 to crdroid 3.6. Then flashed an earlier version with 1600 which worked, then flashed 3.0 again. Now it works. Always wiped the caches.

Weird you had to go through all of that to get the new version working. I'm unsure why. You're obviously not one as the 1.6ghz is working for you,but it has been reported to me that this version does not work for some. The reason is due to the CPU revision I think. Either way,its been reported enough that I will most likely also release a 1.5ghz version as well for the next build.

     */

    19-10-2017 * Updated to v6.0 * Changes are in red or can be seen at the bottom of this post in the changelog: I am always applying patches to hopefully improve the kernel,so check out the "Patches and tweaks applied" section for a better view of the changes as well.

    Notes
    • ALWAYS read the "Known Issues" section before flashing. I will add issues I have noticed or have been told about. Some may be VERY important. If you fail to do this and experience an issue that is listed I can not help you!
    • SELinux is set to permissive in this kernel. You can change this to enforcing at boot if you wish via an app like Kernel Adiutor-Mod
    • About voltage control: Setting frequencies that are unstable are going to cause lockups,freezes and reboots. This is NOT a fault in the kernel. My suggestion is to move the voltages up or down slowly (+/- 25) until you find some stable voltages that you're happy with.
    • Enough people were having problems with the 1.6ghz overclocked version that I've decided to release a non overclocked (1.5ghz) build as well. I would recommend trying the 1.6ghz and only if you experience a bootloop or instability then use the 1.5ghz version. I will not keep older versions of the 1.5ghz build up. Only the latest.
    • Having troubles deciding on a CPU governor or an I/O scheduler? Here is an amazing guide. All credits to Saber. Be sure to hit the thanks button. He obviously put a lot of time into that.
    Features
    • Based on the latest Samsung kernel sources
    • Built an updated Sqlite3 (from version 3.9.2 -> 3.19.3 that will be pushed along with the kernel install (you can verify this by running "sqlite3 --version" in a terminal emulator before the new kernel install and then again after)
    • Compiled with self-built (ct-ng) UBERTC 8.0
    • Patched Linux to latest 3.4.113
    • Unlocked CPU frequencies: 200MHZ and 300MHZ
    • GPU overclocked to 600MHZ
    • CPU Overclocked to 1.6GHZ
    • CPU voltage control ( Max voltage =1500mV. Min voltage =600mV)
    • DriveDroid support (add sysfs entry for cdrom to LUNs)
    • Implemented zen-tune v4.5
    • Added CPU boost driver
    • Added PIE net scheduler
    • Added support for USB keyboards (You need This app)
    • Reduced vm_swappiness from 60 to 20
    • Added I/O scheduler switcher by sultanxda (changes the I/O scheduler for a specified request queue to Noop when the screen turns off in order to improve power consumption while the screen is off)
    • Added Fsync on/off
    • Added dynamic fsync
    • Added Dynamic management of dirty page writebacks (allows to have two different intervals for dirty page writebacks and to dynamically manage them when the system has been resumed (it's active) or when has been suspended - Not adjustable via Grarak's Kernel Adiutor app)
    • Proc: much faster /proc/vmstat
    • Full CIFS support ( Modules will be pushed with kernel install )
    • Introduced new flag WQ_POWER_EFFICIENT for power oriented workqueues ( Allows for power saving if selected in Kernel Adiutor ETC. )
    • Added /dev/frandom support ( It is yet to be implemented properly yet however )
    • Properly enabled faux123's powersuspend v2.5
    • Fading LED's
    • Enabled graphite
    • Enabled AIO
    • Readahead set to 512 (from 128 default)
    • Reverted "Enabled arch power" (There will be a switch to enable/disable this in the next build)
    • Many build flags for optimization
    • Added optimization flags for the GPU
    • Many more features being worked on and coming soon

    Patches and tweaks applied include:

    - Updated ARM topology and added cpu_power driver

    - Fixed all the CPU governors to work properly with the Move get_cpu_idle_time
    - cpufreq: Introduce new relation for freq selection (It selects the frequency with the minimum euclidean distance to target. In case of equal distance between 2 frequencies, it will select the greater frequency)
    - cpufreq: conservative: Set MIN_LATENCY_MULTIPLIER to 20
    - cpufreq-ondemand-Set-MIN_LATENCY_MULTIPLIER-to-20

    Known Issues
    • Setting alucard hotplug along with certain other governors at boot via kernel adiutor etc can cause a reboot after setting is applied. So be certain to set the "delay" time in kernel adiutor or similar to 10 seconds or more,so if you have this you are able to cancel and change after a reboot.
    • There is a chance of some settings being reset after flashing the kernel (quick setting,sound,statusbar etc.) This is rather insignificant and all settings that have been changed can be set back in minutes.

    Installation
    I HIGHLY recommend that you do a full backup before flashing this kernel. I am not responsible if you lose any or all of your data.

    1.Download "Spookcity_Kernel-N"
    2.Place the zip onto your phones storage
    3.Reboot into recovery (Volume-Up + Home + Power button)
    4.Select install
    5.Flash the downloaded kernel
    6.Go back a few times in TWRP Select wipe -> Advanced wipe and wipe Dalvik/Art cache and the cache partition.
    If you do not do this you are very likely to experience strange issues.You have been warned.Do not report problems if you did not do this.
    7.Reboot
